Im having a little trouble setting up the diffs in my cyber10b... this is my first 4wd car, and first to use ball diffs (comming from a rustler VXL) so it might be pretty elementary.
I built everything as per the manual, and used grey grease on all the dog bones & CVD's, and after a 5 minute bash in the dirt the whole driveline was caked with grit and binding up quite badly. Pulled it all down and cleaned it all out, but the diffs were still quite stiff and "gritty" in their motion. The 8 very small ball bearings under the diff screw were also covered in dirt, so I pulled them down and cleaned it all out. Bearings are still good, bevel gears too... without the screw in and just pushing the diff together it spins freely, but with the screw in (and 8 small ball bearings with a
small ammount of grey grease) and the tension set so the bevel gear cant spin with two allen keys holding the steel outdrives still.... it still has a really gritty, far from smooth feel when spinning just one outdrive at a time.
This is only really happening with the rear diff, fronts not too bad... there is definitely no dirt at all in there, so its got me stumped.
Any ideas? If anybody knows a better way to set the diffs up I would love to know
Thanks
